According to an embodiment, a steering wheel includes a covering material, wherein the covering material includes back lighting under the covering material.

According to an embodiment, a steering wheel material includes a covering material, wherein the covering material includes back lighting under the covering material.

Embodiments of the present invention will be described below with reference to the drawings.

A steering wheel 1 includes a steering wheel rim 3 connected to spokes 4. The rim 3 and spokes 4 can be enclosed by a casing 110. The casing 110 can be a foam material or other material known in the art with similar properties, such as shape-retention and/or softness. For example, the casing 110 may be made of polyurethane (PUR) foam.

The steering wheel 1 is provided on its front part with covering parts 5, 6 that include a covering material 100. In the example shown in FIG. 1, two covering parts 5, 6 are shown. However, embodiments of this invention can be used with other covering arrangements for a steering wheel 1, such as, for example, an arrangement with multiple coverings that cover different segments of the steering wheel 1, or an arrangement with a single covering that covers the entire rim 3 and/or spokes 4 of the steering wheel 1.

FIG. 2 shows an exploded view of a portion of the steering wheel 1 cut along line II-II of FIG. 1 of a covering material 100 according to one embodiment. The covering material 100 may include the casing 110, a light element 120, and an outer cover 130. The casing 110 may be used to provide shape to the steering wheel 1 so that a vehicle driver may easily grasp the steering wheel 1 and control the vehicle. The casing 110 may be made of a foam material that serves as a base for the covering material 100. The covering material 100 may include a plurality of light elements 120 and/or a plurality of outer coverings 130 that are arranged in multiple layers. Furthermore, the steering wheel 1 may include additional layers between the outer cover 130 and the rim 3 and/or spokes, such as, for example, insulating layers or other layers to aid in driver comfort or feel. By way of example, a layer including a temperature controlling substance may be included.

The light element 120 may be provided to serve as a source of light that is emitted from the steering wheel 1. The light element 120 may be located on top of the casing 110 and underneath the outer cover 130 to provide back lighting of the steering wheel 1. The light element 120 may be electroluminescent mylar, electroluminescent tubing, at least one discrete light emitting diode (LED), incandescent material or wires, fiber optic material, lit acrylic, or other suitable light emitting materials and devices known in the art.

The light element 120 may include a single light element or the light element 120 may include a plurality of light elements. The light element 120 may be arranged so that the entire rim and/or spokes of the steering wheel 1 may be lit by the light element 120, or the light element 120 may be arranged so that portions of the steering wheel 1 may be lit. For example, a plurality of light elements 120 may be arranged to light separate sections of the steering wheel 1, or a plurality of light elements 120 may be arranged to light a single section of the steering wheel 1.

The light element 120 may be attached to the steering wheel 1 in any suitable manner. For example, the light element 120 may be attached to the steering wheel 1 with glue, snap-in fasteners, screws, tacking, sewing, or any other suitable fastener or mechanism.

The light element 120 may be arranged to provide continuous back lighting, pulsed back lighting, or non-continuous back lighting of the steering wheel 1. The light element 120 may be arranged to provide back lighting with an effect, such as, for example, flashing lights, colors, patterns, and other effects known in the art.

The light element 120 may provide back lighting of the steering wheel 1 by emitting light that passes through the outer cover 130. The outer cover 130 may be arranged to permit light to pass through the outer cover 130 by providing holes or perforations 132 in the outer covering. The holes or perforations 132 may occur naturally in the material of the outer cover 130 or may be artificially provided during manufacture of the outer cover 130 or covering material 100. When the outer cover 130 is made from a woven fabric, such as cloth, the outer cover 130 may be arranged to permit light to pass through the outer cover 130 by permitting the light to pass through gaps in the warp and weft of the fabric. The outer cover 130 may be arranged to permit light to pass through the outer cover 130 by providing a thinned area 134 of the outer cover 130 where the thickness of the outer cover 130 has been arranged, minimized, or reduced to allow light to be transmitted through the material of the outer cover 130.

FIG. 3 illustrates a steering wheel material according to another embodiment. The steering wheel material includes a covering material 100A that may be further treated so that a sealant material 136 is provided on the outer cover 130. The sealant material 136 may fill gaps, holes, or perforations 132 in the outer cover 130. The sealant material 136 is configured to permit light emitted from the light element 120 to pass through the outer cover 130. The sealant material 136 may be a clear or translucent material such that the material 136 is capable of allowing light to pass through.

The covering material 100A may be further treated such that other suitable materials are provided to fill gaps or perforations 132 in the outer cover 130. The other suitable materials can still permit light from the light element 120 to pass through. The other suitable materials may be opaque, comprise a color, comprise multiple colors, and/or comprise different textures.

The outer cover 130 may be made of any suitable covering material, such as natural leather, simulated leather, polyurethane, thermoplastics, vinyl, cloth, wood, or other materials known in the art. The outer cover 130 may also be made from a clear or translucent material. The outer cover 130 may be made from a luminescent or phosphorescent material that is activated by light emitted from the light element 120.

By providing a covering material 100 that provides back lighting for a steering wheel 1, additional design options are created for a steering wheel 1. Additional decorative techniques may be used by customer designs studios. Furthermore, customer satisfaction with a vehicle may be increased with innovative designs of the covering material 100. The covering material 100 may be used for cosmetic functions and/or utility functions, such as, for example, communications or warnings from various vehicle systems. In such utility functions, effects of the light emitted from the covering material 100 may be linked to various vehicle systems.

For example, the back lighting provided by the covering material 100 may be used in conjunction with the systems of a vehicle to provide various functions. For example, the back lighting provided by the covering material 100 may be used in conjunction with a collision avoidance system of a vehicle to provide a warning. In another example, the covering material 100 may be used to provide a direction indication in conjunction with a vehicle's turn signals. In another example, the covering material 100 may be used in conjunction with the tachometer. In another example, the covering material 100 may be used to provide a shift indication for the driver of the vehicle. In another example, the cover material 100 may be used to In another example, the covering material 100 may be used in conjunction with a navigation assistance system of the vehicle.
